You know, it's funny. Years ago, this whole issue of rebirth, the accepting/rejecting/agnostic approachs, seemed so important to me. I felt I had to have some clear position on the issue, as if my practice could not progress without having some certainty first.
Now it really feels like a non-issue. Whatever is, is. Practicing kindness, insight into impermanence and not-self, developing equanimity & concentration: this is all that matters now. My white-knuckled grip on the need for certainty over doctrinal issues has somehow dropped by the wayside. Maybe there are answers for certain things. In which case, good. Maybe for other things there are no factual answers to be had. Just as good. Wait and see.
I'm starting to see the value behind Seung Sahn's admonition to "always keep don't know mind."
